Growth Advisory Retainer

Senior marketing strategy on a monthly retainer

A lighter-touch alternative to a full Fractional CMO engagement: a regular strategy call, async support between calls and a monthly review — for a predictable monthly fee, with no long lock-in. Apply once, and I'll send a tailored proposal and a manual invoice.

What is a Growth Advisory Retainer?

A Growth Advisory Retainer is a monthly subscription to senior marketing judgement: scheduled strategy calls, asynchronous review of plans and campaigns, and quarterly priority setting. A Growth Advisory Retainer suits businesses that already have people executing marketing but need an experienced strategic lead to keep the direction and the numbers honest.

The gap

You want senior judgement, not a six-figure hire

Most SMEs sit between two options: muddle through without senior marketing direction, or commit to a full-time Marketing Director at £70,000–£100,000 plus the cost of employment. The Growth Advisory Retainer fills the gap in between.

You get the decisions that matter — what to prioritise, where the budget should go, what to stop — on a rhythm that suits your business, without owning a full-time role or a costly agency retainer. It is the most accessible way to put a Chartered Marketer in your corner.

What you get

What's in the retainer

Every tier is advisory — strategy, direction and review — billed monthly in advance with no setup fee.

Regular strategy calls

A scheduled call every month, fortnight or week depending on tier, focused on the highest-leverage decision for that period.

Async support between calls

Email or a dedicated channel for questions, quick reviews and sign-off, so you are never waiting weeks for a steer.

A monthly review

What marketing produced, what to change and where the next pound of budget should go — in plain commercial language.

Playbook library access

The full set of MCG frameworks, audit checklists and planning templates, applied to your situation as needed.

No long lock-in

Month-to-month, invoiced in advance. Change tier with a month's notice or pause for a quiet period.

Pricing

Fit

This is right for you if

  • You turn over roughly £1m–£10m and want senior direction, but a full-time Marketing Director does not yet add up.
  • You have an in-house marketer or an agency that needs a clearer brief and someone senior holding it to account.
  • You want a predictable monthly cost rather than open-ended project fees.
  • You value independent, Chartered judgement over an agency with media to sell.
  • You want the option to scale up to a Fractional CMO engagement when the work justifies it.
In detail

How the retainer works in practice

The detail behind the tiers: what the calls cover, how async support works and how progress is judged.

What a strategy call actually covers

Each call is built around the single highest-leverage decision for that period, not a status update. That might be reallocating paid budget after a quarter's data, sharpening a proposition ahead of a campaign, deciding whether a channel deserves more or less spend, or making a hiring call.

You leave with clear next steps, an owner for each one and the reasoning behind the decision written down — so the rest of your team or your agency can act on it without you translating.

Async support between calls

Strategy questions rarely arrive on a schedule. Between calls you have direct access for quick reviews, sign-off and steer — a campaign variant, a landing page, a reporting question, a supplier proposal. The point is that you are not waiting a month between touchpoints for a senior view.

Async is advisory: direction and review, not delivery. If a piece of work needs building, I help you brief the right person for it — in-house, agency or from my network.

The monthly review

Once a month you get an honest read on what marketing produced against target: cost per qualified enquiry by channel, conversion rates and pipeline contribution where the data allows, with a clear recommendation to increase, hold or cut spend.

It is written for a board audience, uses the same definitions every month, and is the thing that keeps the retainer accountable rather than a subscription you forget you are paying for.

Scaling up from the retainer

Many businesses start on a retainer to test the working relationship and move up to a Fractional CMO engagement when the volume of decisions justifies more days a week. The transition is seamless — the strategy, the reporting and the working rhythm carry straight over.

If the opposite turns out to be true and what you need is delivery, not direction, I will say so and help you find the right resource. The retainer is not a trap; it is the most flexible way to start.

Questions

Frequently asked questions

How is the Growth Advisory Retainer different from a Fractional CMO?
A Fractional CMO owns the strategy and manages the team on one or two days a week — a leadership engagement for businesses ready to hand marketing over. The retainer is lighter-touch: a regular strategy call, async support between calls, and a monthly review. It is for businesses that want senior judgement on tap and a predictable monthly cost, without a full engagement. Many clients start on a retainer and move up to a Fractional CMO when the work justifies it.
How much does the retainer cost, and how am I billed?
Tiers start at £500 a month (Essentials), £1,000 (Growth) and £1,500 (Scale), invoiced monthly in advance with no setup fee and no long lock-in — the retainer runs month to month. There is no automatic payment taken on this site: apply, I send a tailored proposal and a manual invoice, and you pay by bank transfer.
What happens in the monthly strategy call?
We work on the highest-leverage decision for that period — a channel allocation, a proposition, a piece of measurement, a campaign brief or a hiring call — and you leave with clear next steps and an owner for each. Between calls you have async access for questions, reviews and sign-off, so you are not waiting a month between touchpoints.
Do I still need an agency or in-house marketer?
Usually yes, and that is the point. The retainer gives you the senior direction that decides what the agency or in-house team should be doing. If you do not yet have delivery capacity, I can help you brief and select the right supplier from my network — but the retainer itself is advisory, not delivery.
Can I change tiers or pause the retainer?
Yes. Move up or down a tier with a month's notice, or pause for a month if you have a quiet period. The retainer is designed to flex with your marketing rhythm rather than lock you into a fixed commitment.
Do you work with small businesses and sole traders?
Yes. MCG offers agency-style delivery with the flexibility of working directly with a freelance marketer. You do not need a marketing department or a large turnover to start. A website rebuild, a focused campaign or practical advice can be a standalone piece of work.
How much is a full website rebuild?
The standard website rebuild is £1,000 fixed for up to 40 pages, including structure, design, core page copy, technical SEO, enquiry forms and launch. Care is optional at £100 a month. Ecommerce, bespoke applications, complex integrations and third-party costs are quoted separately before work starts.
Can I hire you for a one-off project?
Yes. You can book a website rebuild, an SEO project, campaign work or a marketing review without taking an ongoing retainer. We agree the work and the price in writing first. Ongoing support is available if you need it afterwards.
Who will actually do the work?
You work directly with Samuel McGarrigle, founder of MCG Growth Marketing, with an MSc in Digital Marketing Management and MCIM membership. Samuel plans and delivers the work, and can work alongside your existing team or suppliers when needed.
Where do you work?
MCG is based in Cheshire and works with businesses across Staffordshire, Shropshire and the wider North West, with remote support available UK-wide.
